strengthening lag screw in wall
hey all
I setup a pull up bar in my garage, and i had to drill four holes in my wooden studs to install it with big lag screws.
the screws are in ok, and i can lift my weight on the pull up bar no problem...but the screws still twirl around in circles and i don't trust the setup. Is there a way i can get the screws in there tighter or more solid ?
I was thinking using some kind of poly filler in the holes where the screws went, and then put the screws in behind them. Would that work? Any better ideas?
Thanks in advance

If the screws are spinning...I don't know how they don't pull out? Sounds like the holes were drilled too big.
I'd take some lengths of bamboo skewers or similar, coat them in glue, put 2 or 3 of them in the hole, then tighten the lags back in...let them sit for a day before use.
Wood filler is normally too brittle to work well for heavy loads.

thanks a lot, i think im going to try that...it doesnt pop out because they're pretty long screws through the wood, but i might have drilled the holes a bit further in than what would give the screws enough force...they only swirl around with a nut tightener, but still its more than im comfortable with.

Reduce the size of your pilot bit so the lag has something to grab into. Too large a pilot makes for easy screwing, but you aren't accomplishing anything.
