Hi guys.
Finaly I built myself a lam grinder to replace the jig I used on my oscillating spindle sander.
That thing worked well, but I couldn`t get precision with it. Anyways..... I built this lam grinder,
very simple design. Seem to work well. The test pieces I ran through it came out consistent and square,
no waves (like I got from the spindle sander jig) and since I use 50 grid sandpaper on the drum, the lams
come out rough and ready for glue-up. So I`m happy :goldtooth:
I guess some of you had this kind of thing at the beginnig (or maybe using a self built grinder to this day)
so I`d love to know what you think and if there`s anything important I should know or take into account when using it, let me know.
Dor

Looks better than mine. All I have is kenny’s phone number :biglaugh:
Nice work. My only advice would be to do a test piece each time you use it. Either the frame being made of wood, there’s always a chance of movement.

I got one of those! [ You are not allowed to view attachments ] Looks like you have wood screws holding your frame together, I ended up putting a 5/16 bolt and lock nut through each joint for rigidity. I also had to change the table adjustment, I was getting side to side slop with the bolt like yours. You might not have that issue, seeing that your drum is centered over the adjuster bolt.

:thumbsup: cool to see some improvising for power tools.

I have one of these that I built several years ago. The problem I have with mine is the inability to feed material through at a constant/steady feed rate. If you speed up, slow down or pause while feeding the wood it will cause a dip or ripple in the wood. Has anyone adapted or designed a feeder on a grinder like this? If so I would like to see what was used and how it is set up.
