2019 what did ya do today....

[Roy from Pa]

So that's why I started itchen up a little bit ago?

Ya ever think about gluing 3 or 4 full length thinner belly lams together to get that bend ya want at the riser?

Ya could do away with the splice all together...

LOL.  Just messing with ya.  I only work with the stuff outside now after hearing what it did to you. 

[Roy from Pa]

LOL

There will never be IPE in my shop again.

Yeah, I have thought about doing that exact thing quite a bit.  But I'm not setup to taper a full length piece. 
And I would probably need 4 lams with ipe as it doesn't bend even at thin dimensions. 
And that splice doesn't take much time.  It looks more complicated than it is. 

You think the lams would bend enough to give me this much deflex?

[Roy from Pa]

Yes and the arc / bend would be a  really smooth transition.

1/8th thick lams would bend really well, even 3/16th thick I'd bet.

Two thicker lams here bend decent and that's not much bend.

I'm liking your angular design there Ben ! 

[Shredd]

Whatcha got going on there Ben...  I have been entertaining the idea of having some small recurves at the tips...

   Stuff is going on around here...  Got some lights so that I don't have to wait on the sun to get right...

   Modified my thickness sander...  It does not have a feed belt and the friction was an issue with lams on a sled...  The sled would stop and the lams would slide...  So I installed some rollers under the feed rollers and shortened my granite table to just under the drum...  Added some table extensions made out of plywood...  Seems to work great...  What a pain in the a$$ though...  Everything has to line up just right...

   I swear...  I think I spend more time making jigs, modifying and tweaking tools than building bows...

[kennym]

Finished a recurve form, glued up a riser blank, milled all the lams and scarfed together . May glue a bow tomorrow pm

[Roy from Pa]

Shreddy that's a dumb sander if I ever seen one.

[Bvas]

Sat in the rain waiting on deer. So far our “blizzard” is a bust. Rain rain and more rain.
Three more weeks(or a buck on the ground) before I think about starting a bow.

[Bvas]

Shredd, is that a homemade thickness sander? 

I have been thinking of building one. But thinking of having the drum do the traveling and the table be adjustable. Then I could have an infinit amount of adjustment in taper. I just haven’t come up with a durable/reliable/affordable track system.

[Shredd]

   Geez thanks Roy...   

  I will put this sander up against any sander out there for consistency and accuracy...  Being there is no belt it operates like a bench planer...   The wood rides between a solid granite table and the drum...  A belt can have inconsistencies...  Some guys wonder why their bows are 5# over or under weight...   Inconsistencies  along the laminations could be one of the factors why they are missing their mark...  Especially when you are reading the butt of your lam and the middle of your lam is 3-5 thou off its begins to add up...

   Bvas...  This is an older Wood Master sander...  You can make one but it would be a lot easier and probably cheaper in the long run to buy one...

[Shredd]

  Hey Bvas...  Do you have an Edge Sander??  Because if you do, you can make a jig to sand laminations...

[Bvas]

No Shredd. I’m tool poor.

I have a drill press that I use as a spindle and a hand held belt sander. These get me by. But as I build more bows, I want more toys. 

[Crooked Stic]

Can you use taper sleds thru it? Mine has a feed belt and stiffness of the sleds seems to get rid of incosistencies
. I kinda like to check my lams from one end to the other to just to be sure.

[Shredd]

  Good point Stic...  Yes I can run sleds through it...  That's why I did the modification...

[Shredd]

  Bvas...  Look for a used Harbor Freight 6 x 48 sander and turn it on it's side...  Works great...

[skeaterbait]

Damn Lonnie...  Whatcha got going on there??  Looks pretty cool...  Love to see a DFC on that sucker...

Here is the DFC, to the best of my understanding on how to do it. Just measure draw weight at each interval and chart it? I didn't go past 30" because I didn't like the string angle and I was skeered.

Now maybe someone can explain why we do this?

[Roy from Pa]

Now maybe someone can explain why we do this?

I think to look professional?

I duno:)

[Crooked Stic]

It got a rise there on the bottom end and kinda smooths out then starts picking back up around 28 in. Thats good. Ya do it to check how smooth it is.and Bottom end loading is good for performance. If the string angle was getting close to 90 % then she was gonna start stacking. Tip wedges would help that. I am not up on the stored energy part of it though.
