1. Yes the red "thing" is the knob used to adjust
the resistance.
?
2. Its about 1/4 turn so there is still some
resistance & 1/2 turn lets it go fairly loose.
?
3. The reason you can't mount it that way is the
hydro unit will be in the way when long stock is clamped in the vise due to the
plumbing of the unit.
?
I have seen the hydro units mounted in front by
using the bolts on the gear box & bolted to the frame but I can't find the
site I saw it on.

Re: Hydralics On 4 X 6 Cheap
Alan Rothenbush
Here is the url for the hydro cylinderRod; Nine bucks ! That's pretty cheap, all right, and has me a whole lot more excited about yet another modification to a machine. ( My wife keeps asking "yes, that's nice dear, but when are you actually going to make something with your tools, instead of just <improving> them all the time?") A few questions, if I may. 1. I guess the big red "thing" is part of a valve, used to adjust the hydraulic resistance, right ? 2. If so, how much rotation of the knob is required to go from free to "as stiff as you'd ever need". 3. Could the whole setup have been fabricated such that the cylinder lays flat, in roughly the same position and orientation as the spring ? You see, just yesterday I came up with a nice square stand that JUST fits a particular space in my very cramped shop. The stand is about 16 x 24 x 20" high. ( It was 28 inches high, but 3 hours of cutting followed by 2 minutes of welding cut it down to 20 inches, and so the bandsaw now fits under the bench.) There's really no room to hang things out the left, as you have done, or the stand won't go into the space. Things could go inside the angle iron ( the frame is just 12 pieces, welded into a box ), but if a lot of rotation of the valve is required for operation, that could get old in a hurry. Any thoughts ? Alan -- Alan Rothenbush | Before me things create were none, save things Academic Computing Services | Eternal, and eternal I endure.

Thanks for the comments. I don't have a site right
now but want to work on getting one. The hydraulic unit is what is used for
sporting equipment like stair steppers, I'll post the site I purchased it from
below. Definitely get?a Lennox?10-14 bi-metal blade you won't regret
it. They cut way faster & last longer than the carbon steel blade?the
saw?came with.

Hi Rod,
Nice pics and work. Do you have a site with the info on this mod? Is that hydraulic cyl a door closer? sorry to be so out of it, but I just got this thing and am learning. BTW, do the 10-14 bimetal blades cut faster or just last longer than the one that came on the saw? Trying to decide if I should replace before it wears out. Seems to work pretty good.

I'm currently using an 18 TPI blade. I bought it to cut a bunch of square tubing, then was too lazy to change it before cutting some solid stock. The solid stock cut just fine, great in fact, better than the 10-14 I had been using. So on it stays. Aluminum is a different matter, though. The coarser blade jams much less frequently (if at all) than the finer on Al. But an aquarium pump and coolant is in my immediate future; we'll see if that helps the jamming problem.

Re: Downfeed control

I think any of these saws will cut faster with added pressure on the blade. The limiting factors are power available and temperature elevation of the blade. As long as the blade does not stall and the temper is not drawn from the blade, everything should be ok. (wear of the moving parts may be greater) The above is my opinion and may be worth the proverbial two cents! 8-) Leo (pearland, tx) |

And it's not that it won't cut without added weight, but cuts WAY faster with it. I would guess that my current blade has 100 hours on it, more or less, and even abusing it this way, shows no sign of needing replacement.

What pitch blade are you using at this time?
Another feature of the hydraulics is you should be able to use a coarser blade
& control the downfeed so it does not strip the teeth off. Maybe your saw
head is binding on the shaft it swivels on? Good luck with your trouble
shooting.

That still leaves my original query .. why do I require additional weight whereas everyone else with seemingly identical machines do not ? ... Oh well, I'm about to make another stand for mine, which will require a complete disassembly. I'll stare at things then and maybe find a source of friction currently unknown.

Just make sure you make the fit as close as
possible, the tighter the fit the better the bracket will work.

Well I guess I am just spoiled that way: )?I
like having the control on the saw head not just going down but holding the head
in place while moving the stock instead of lifting the head all the way up. Now
I also can?ADD weight on the saw head & not have to?figure out
how?much weight I have on it I'll just adjust it with the hydraulics.

Re: Downfeed control
Alan Rothenbush
After seeing Rod's wonderful workmanship, it occurs to me that I must
be doing something wrong. You see, I have no need to slow things down, on the way down. In fact, I've removed that useless spring and its flesh-eating handle. In fact, I routinely ADD weight to cuts; Al, mild steel and even tool steel ...

I made part 1 out of solid stainless stock but the
same desired effect could be achieved with some pipe the is the size of the
hydraulic unit body.?1/4" steel strap rolled to fit then dremmel the slots
into it if you don't have access to a mill.
