Re: Some questions on the Overhead Guard
Martin, would love to know if you have a more detailed thread on the construction of your guard?
?
Joe, I've only noticed the "tab" (with the allen head bolt) fairly recently, and couldn't see it previously
on the zoomed in pics of your SUVA guard.
?
It seems to me, that this could be some kind of feature which could make the guard rigid...
though from what you mentioned on the Creek recently,
I'm getting the impression that it's simply there to stop the guard from lifting too high?
I'd love to know if it could be made solid rather than floating, and from looking at various pics of guards on the web,
kinda gotten keen on the dump truck lever designs for some reason or other.
?
Cheers
Tom

I made an overhead guard for my T17 with help from my welding friend. 3” and 2 1/2” tube. Bought a Suva blade guard. Looked at a lot of aftermarket guards but could find nothing that fit the saw.
This was an expensive undertaking but no wiggles on this one either!

Re: Some questions on the Overhead Guard
Mac, that is a really nice setup. I planned on using a 2x2 x 3/16 tube for my main vertical support, but I think you may have changed my mind to use a 5x5 x 1/8 tube that I have here left over from another project.
Might even increase my horizontal tubes to 2 1/2 - depends on what I find in the remnant pile tomorrow at the steel shop.
I really like the beefy look and for that I am often accused of over-building, but I also hate stuff that wiggles.
I like the idea of the jacks on the bottom too.
Thanks much for the pictures.

Kamal, thanks for the link to the video - that helps a lot also.

(Was supposed to get the saw yesterday - but it never showed up so will hope for this coming week. At least the driver was nice enough to call and told me they did not have enough time for my stop.)

Re: Some questions on the Overhead Guard
FYI Unit was built with 700 series Felder horizontal gray post the rest of it. I’m manufactured myself. The horizontal column is lined with HUMW vertical post is 6 x 6 tubular steel has jacks on the floor and bolted to the body of the machine 50 inch rip capacity 22 inch clear crosscut? Dust 80 to Hundred. Hood. is quickly removable Or the whole horizontal assembly just slips out when I’m shaping. Over arm doesn’t wiggle. All welded and bolted construction. Maybe 15 years old Mac,,

Re: Some questions on the Overhead Guard
The blade on Amazon looks like it’s already punched for Felder brake. True? - thx

Hi Philip,
I don’t like to shoot in the dark but what Steve mentioned is a distinct possibility. I do not have much experience with Hammer but Felder designs commonly use an overload relay with an adjustable current setting. This could be the source of your issue. In my KF this relay resets itself, after cooling, if in auto reset mode.
In Felder schematics K1 typically controls the motor and F1 (overload relay) is physically attached to it. If you are capable of troubleshooting with a multimeter it is easy to confirm that the overload relay has tripped.
You can call Felder for assistance or send me a PM if you need further help. I still would need a copy of the schematic to assist.

I forgot to mention that you may also want to check for any loose electrical connections since you have had vibration issues.? This could also cause tripping of thermal overloads.

Re: Some questions on the Overhead Guard
Thank you Mac and Rusty for your perspective. This is what I was looking for.
?
I always like to explore ideas and concepts and am, at the same time, mindful of skill sets, knowledge and equipment required to bring the idea to fruition. Your input will be useful in my endeavors.

Re: Some questions on the Overhead Guard
Denno,
?
Mac's answer to "how long did it take?" is right on point. ? ?I'm sure that I had that project brewing in the back of my mind for several weeks before I started collecting materials and mocking it up. ? If you want to put wheels on the bottom like I did, that's a great place to start as it will set a few dimensions for you. ?The wheels on mine are there to reduce friction but also function as a hold-down device. ? The sticky-back scale I have mounted on the vertical adjustment arm is calibrated about 1/16" from true. ? This means when I set my guard to 3/4" for example, the wheels will sit 11/16" above the table surface. ?When my workpiece rolls under them, ?I get about 10-15 lbs of down force. ? This gives me nice constant downward pressure on anything remotely uniform in thickness. ? I looked into all types of wheels for this project; skateboard, luggage, RC car, etc. but eventually found what I wanted in an inexpensive caster wheel. ?2" OD, 1" wide and soft non-marking rubber
?
?
Builds like this look complicated when viewed as a whole but like anything else, ?it is just a series of steps - none of which are overwhelmingly difficult. ?Once you have some parts in your hands, it becomes much easier to move the project along. ?The question and potential solutions to "how does part A connect to part B?" will present themselves in manageable bites. ? ?I didn't make a drawing for this. ? I took some rough dimensions and mocked up some things in scrap wood just to help me visualize all the required connections and articulations. ? I also spent an unhealthy amount of time on the internet looking at both shop-built and commercial versions of "overhead tablesaw guards". ?I printed a few pics of the assemblies I liked and went to the bench and started building. ? I'm sure it took it a good week to collect all the bits for this and get it assembled but like Mac said, ?many of us enjoy this kind of work with no hard deadline, strict budget limitations, and/or client accountability. ?Of course I suspect we all find it rewarding to use something daily that we built with our own hands. ? This project is also not hard to justify for the added safety factor so I encourage you to not be intimidated and just get started on your own version. ? ? ? ?

Re: Some questions on the Overhead Guard
I have been very happy with the Forrest blades I have and they have done a bang up job of sharpening the Felder blades too.

Philip,
What do you mean by “after 5-10?minutes with he table saw on the power switch flips”
On felder, no on/off switches flip on their own. Do you mean that the saw just turns off? If not a picture would help.
Also by power switch, do you mean the switch to turn the saw on or the main power cutoff? You use, power switch, more than once do it always mean the same switch.
Another issue is if I bump it it will cut off, (but that may be a safety thing?
Bump what? The switch that turns the saw on?
I would also need the electrical schematic to offer any help.

I have a 2002 Hammer C3-31 combo machine and it was a floor model and wasnt able to try it out till I rented a truck and a 2 ton fork lift and get it in my shop. When I did I discovered it was very underpowered and had a reverberating vibration.? I talked with the Felder folks and after much back and forth they agreed to send two 3 KW motors to replace my 2.2 KW motors, but no instructions and I had to install and hook up myself. ?So I commissioned an electrician once I did the work of installing motors.? He as able to get it running and ive been using for years, but I have been experiencing the following issues:? after 5-10 minutes with he table saw on the power switch flips and I have to wait 5 or more minutes before it will engage when? flip the main power button on machine.Another issue is if I bump it it will cut off, (but that may be a safety thing??. ?I mostly remedied the vibration with a dampening blade from Forrest.??Can anyone offer and advice/guidance?? Thanks in advance.? Cheers!

Re: Some questions on the Overhead Guard
Hi Denno
When looking for blades for my Felder saw, I found Freud must make a lot of the blades for Felder.?
Some seemed to be the same spec or so close that it made no difference (to me at least, as it may have only been a small difference in the tooth count).??
With the market being so small here in NZ, there isn't that much of a range available that's available ex-stock.
Good luck with getting everything you need as soon as possible so you can start making with your new saw.
Cheers

Re: Some questions on the Overhead Guard
Howdy folks. I’m preparing to downgrade my 49” k700s to 31”. I ordered a table and bar, but the guard holder is more expensive than the entire guard assembly on the Felder Shop, which isn’t cheap.
So, I’m left the choice of building a holder or chopping the 49 down. I HATE the idea of cutting it, but i want it to be sturdy and don’t trust myself to build one to my standards.
Does anyone know, or can someone quickly measure, the length of the arms on the 31? I’m thinking i just need to remove 18” and re-drill/slot-out new mounting holes but I thought it would be smart to check with you guys.
Or…. Better yet… is there someone in California who wishes they had upgraded the capacity on their saw? I’d be open to trade!

Re: Some questions on the Overhead Guard
Jacques It’s a good way to get your hands dirty that’s for sure. Rusty obviously has numerous skills in Metal working and other skills One finding the materials developing a design ability to cut weld on drill mill grind That’s all the exciting part of it. If I get a chance I’ll take a picture of the overhead saw guard I built.? My compelling reason was I hate shit that wiggles metalworking that is. Mac,,, Designing and building for 50 years
