I recently bought the Hongdui-Katz/Moses router plane and had decent luck using it for some tenons. However, I'm running into some real trouble trying to cut grooves for a box project. I've noticed a couple of major issues: first, the depth setting feels overly finicky, where I can start a groove lightly, but the blade abruptly digs deeper than intended, making it frustrating to maintain control. Secondly, the fence seems to loosen up while I'm cutting, which really ruins the groove. I've read that router planes aren't great for cutting grooves initially, but I'd like some advice. Is this just a rookie mistake on my part or is it a flaw with the tool? I'd love any insights from fellow handtool users who may have faced similar challenges.

Make sure the router is locked down properly. If it keeps loosening up, you might not be securing it right. Also, ensure the blade is super sharp and the base is on a flat surface. Otherwise, if you apply too much pressure, it can dip deeper than expected. The router should be used with light passes for best results.
You’re not alone in your troubles. I think many beginners face similar issues. But ultimately, you may find it more efficient to reserve the router plane for cleanup rather than initial cuts. If depth control is being problematic, it might be a flaw in either technique or the tool design you're dealing with.
It sounds like you're on the right track; however, if you're cutting grooves, I’d recommend first establishing part of the groove with chisels before using the router for additional refinement. It might save you some headaches with depth issues!
I've had similar issues when working against the grain. Changing the angle or the direction of the plane can sometimes help with catching. But if you’re set on using a fence, be prepared for some struggle! I typically use my router planes more for final touches after establishing a groove with chisels or a plow plane.
Thanks! I guess I should stick to the chisels for the initial groove cutting. The fence issue is still a pain though.
It seems like you're using the router plane for something it wasn't specifically designed for. It's typically meant for smoothing and finishing grooves rather than cutting them from scratch. You might be better off using a plow plane for the actual grooves, then using the router plane for cleanup afterwards.
That makes sense! I guess I was hoping to skip some steps and got in over my head. Thanks for the tip!
Sounds like you might need to give the fence a good check. If it keeps slipping, it’s fundamentally flawed for precise work. Either way, using a combination of techniques might provide you the best results!

I think I'm experiencing some of that. The locking mechanism seems tricky, and I may be trying to push too hard. I'll try lightening my touch and see if that helps.
