Re: Placement of a Support Brace
Imran, I think what you are talking about is this , The Power of The Triangle. It is one of the strongest forms if not the strongest form. To compress a triangle out of that form only two things can happen, 1. the material fractures or explodes. 2. The joint fails. My guess would be that the joint will fail first. I don't think the actual angle has much to do with it Glen Alpine Moulding and Millwork Inc. Mail: ?? P.O. Box 486 ?????????? Murphys , CA. 95247 Shop: 441 Pennsylvania Gulch Road ?????????

Re: Placement of a Support Brace
¿ªÔÆÌåÓýDavid, ? I figured I will end up drawing this. Attached shows the simple scenario. Assume there is a weight hanging at the end of the cantilever. The cantilever, itself, does not need any support. The cantilever is joined with a M&T to the post. If the only concern is M&T joint, can that be alleviated with a brace? ? If the answer is yes, I show point A (midway) and point B near the end. Lets say, it is possible to add a 45 deg brace from these points to the main post. Is one better than the other or another location is best. ? Imran ? From: [email protected] On Behalf Of david@... via groups.io

Re: Woodworking Shop Rental
¿ªÔÆÌåÓýJason, Jeff & Taylor, ? Thanks for the feedback. I guess $500/month sounded too good to be true but over the long haul $6K/yr starts adding up. Although if you do not have a building sitting around it still is pretty cheap. I guess it works out for both parties. Good to know. ? Imran ? From: [email protected] On Behalf Of Jason Holtz

Re: Storing Big Squeeze Clamp
Thanks, Mac.? I appreciate your comments.? The knife hinges are shop-made which I guess is a Krenov thing because that is the ultimate source of a lot of what I do.?? There was similar feature that did not show in the picture - shop-made full extension glides for the drawers.? I usually use Blum but they did not have an appropriate?size for my design application so I made these?of wenge which is durable but full of splinters. Photo enclosed. ? ? ?Jim ? ?? James H.

Re: Placement of a Support Brace
¿ªÔÆÌåÓýHi Michael, No it is not a mail box application but concept is same. In my scenario, the beam itself is stout and does not need any support however I have an interest in strengthening the M&T joint to handle the weight (downward force) at the open end of the beam. How would you use a brace for this purpose? As I understand, and it has been mentioned here, that brace works better in compression than tension. I do not know for sure what the reason is, but I suspect it is due to the limitation of the wood joinery. Imran On Mar 28, 2021, at 9:12 PM, Michael Garrison Stuber <mtgstuber@...> wrote:

It is typical to add a brace below the cantilevered arm that goes into the vertical post at some angle. My first thought was that the brace will be more effective if it is placed as far away as possible but it is easy to see that will actually have the affect of pulling the arm out of the main post. It is easier to see this by imagining a heavy weight hanging at the end of the horizontal arm. If the brace is placed in the middle of the arm, it looks more like a seesaw and any weight hanging at the end of the arm actually pushes the tenon up into the post. That seems like a better direction for the force. I guess I have never thought about this in detail. It appears to me that if the purpose of the brace is to aid a week arm then it might be best to go completely diagonal but ensure that the horizontal arm cannot be pulled out. But if the arm is strong and the only reason for the brace is to strengthen the mortice then it might be best to place the brace in the middle of the arm. Now the reason I am writing this, would it be better if the brace moved in, just a bit more towards the vertical post? It should increase the upward force even more. So instead of 50% what if the brace is placed at 45%. As long as the tenon is strong it should be better. Correct? Imran -- Michael Garrison Stuber |

Re: Placement of a Support Brace
¿ªÔÆÌåÓýJust slap a 2x4 and call it done ? I hope to hear from mechanically inclined members on this. My intuition has betrayed me before so I could be wrong. However, once I started thinking of the ideal place to attach the brace on a cantilever it seems to me that mid point or a bit less may be the answer. This is for a case, where cantilever does not need any support and the purpose of the brace is to help the mortice & tenon joint.

Re: Changing capacitors on a Phase Perfect
¿ªÔÆÌåÓýJust a word of caution. When discharging a capacitor use a resistor in series to limit the current. Tom, I used a RPC for a long time. The only sound, during braking, that I am familiar with is coming from the machine not the idler. I still get same sound with Phase Perfect. Imran On Mar 28, 2021, at 7:00 PM, tomruth@... wrote:

Re: Woodworking Shop Rental
I don't know.? When I lived in San Diego, I was a member at a maker's space that had most of that equipment, as well as CNC and laser stuff for about 500/year.? Some of the stuff was first rate, some not very well maintained, and there was often a wait for equipment use.? Where I live now, I pay? 500/yr for a similarly equipped? hobbyist space, also with CNC and laser.? No slider but I think everything else on the list is covered.? The real issue is, if you're a production sort of shop, you will have to share machines with other people.? ?I'm slowly but surely building my own shop space--even as "just a hobbyist", having people standing over one's shoulder glaring as you surface rough lumber,? or having to go to a main desk to "sign out" a dado set and brake for a SawStop is annoying at best.? ?Still, it's nice to not have to buy EVERYTHING all at once in order to function.

¿ªÔÆÌåÓýI saw this and it is hard to believe that one can rent this for $500/month. Is this the going rate or there likely is a catch. Imran |
